Alpha particles (helium nuclei) are much larger and heavier than beta (electrons) and gamma (high-energy photons). This means they do far more damage to anything they hit.
However, it also means can't travel very far and can be stopped by as little as a sheet of paper.
Radioactive isotopes that emit only alpha radiation are not very dangerous, the only danger is breathing in or ingesting the isotope.

The mass of a neutron is nearly equal to the mass of what other subatomic particle?
No, an alpha particle is the nucleus of a normal helium atom - 2 protons + 2 neutrons. Therefore, an alpha particle has approximately 4 times the mass of a proton or neutron.No, an alpha particle is the nucleus of a normal helium atom - 2 protons + 2 neutrons.

How much alpha particle is heavier than neutron?
An Alpha particle is composed of two protons and two neutrons, so simplisticly it is heavier than one neutron by the mass of two protons and one neutron. A proton weighs in at 1.672621777(74)×10−27 kg and a neutron a bit more at 1.674927351(74)×10−27 so you can do the maths if u want to see the actual figure.
Which radiation is identical in mass and charge helium nucleus?
process by which a target nucleus can be split into two smaller nuclei upon bombardment
Which particle will have the same mass proton and electron proton and neutron electron and neutron or all three particles?
The masses of all three particles are different The masses of a proton and the mass of a neutron are very close, however. The mass of an electron is much smaller than the mass of a proton or neutron.
What particle alpha or beta is more massive?
An alpha particle is a helium nucleus, consisting of 2 protons and 2 neutrons. Beta particles are fast moving electrons that are emitted from a nucleus when a neutron decays into a proton and an electron. Since 1 electron has 1/1837 the mass of a proton, the alpha particle is roughly 7348 times the mass of the electron.

Which has the smaller mass a particle an electron a neutron or a proton?
Electron!
Does an alpha particle have a relative mass of 1 amu and no charge?
No, an alpha particle has a mass of 4 amu and a charge of +2. It is a helium nucleus. The neutron has a mass of 1 amu and no charge.

Which particle has a mass that is approximately the same as the mass of a proton?
the neutral or no charge particle of an atom:it is located in the nucleus;has the same mass as the proton.
How do the mass and size of an alpha particle compare with mass and size of beta particle?
The mass and size of an alpha particle compare with the masa and size of beta particle in the sense that the alpha particle is significantly larger in both size and mass that the beta and gamma particles. This is why it is called the alpha particle.
Is alpha particle is heavy particle?
An alpha particle is a helium-4 nucleus. It has a mass of about 4 atomic mass units.
Which particle will have the same mass proton and electron proton and neutron electron and neutron or all three particles?
The masses of all three particles are different The masses of a proton and the mass of a neutron are very close, however. The mass of an electron is much smaller than the mass of a proton or neutron.
What are the characteristics of an alpha particle?
An alpha particle has the charge 2+ and the mass 4.
